STOVEPIPE QR CHIIVINEY THIMBLE.

SPECIFICATION formingpart of Letters Patent NO. 745,618, dated December1, 1903.

Application filed January 5. 1903.

Be it known that I, CHARLIE E. HUBBs, a citizen of the United States,residing at Greenville, in the county of Montcalm and State of Michigan,have invented a new and useful Stovepipe or Chimney Thimble, of whichthe following is a specification.

This invention relates to an improved stovepipe or chimney thimble, andhas for its object to provide a simple inexpensive device of thischaracter adapted to be inserted in the opening in the chimney-breast orany other opening where a pipe connection is desired and provided withmeans for effectively retaining the thimble in the opening and lockingthe stovepipe within the thimble.

A further object of the invention is to provide a thimble formed from asingle piece of sheet metal or similar material bent into cylindricalform and provided with one or more inwardly-extending integral stops,whereby the stovepipe is prevented from projecting beyond the end of thethimble and obstructing the flue. I

With these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts. hereinafterdescribed, illustratedin the accompanying drawings, and pointed out inthe claim hereto appended.

In the drawings, Figure l is a perspective view of the thimble. Fig. 2is a sectional elevation showing the thimble in achimneybreast. Fig. 3is a similar view showing a different manner of fastening the pipe tothe thimble. Fig. 4 is a perspective View of a further modification.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 designates a chimney-breast, and 2 the opening therein. 3 indicatesthe thimble, which is preferably formed of a single piece of sheet metalor other suitable material bent into cylindrical form and having itsoverlapping end portions l connected by means of rivets or otherfastening devices at. The thimble 3 is provided with an annular flange6, which bears against the face of the chimhey-breast 1, said flangebeing formed by slitting the end of the thimble to form a plurali'ty oftongues, which are bent outwardly Serial 137,803. on inodel.)

on radial lines, as shown in Fig. 1 of the drawings. One of the tonguesmay remain unbent to form an ear or lug 8, or a number of such ears maybe formed, each provided with an opening 9, adapted to receive a wire10,which passes around the elbow (not shown) of the pipes 11, beingfastened there to in any suitable manner.

The rear end of the LllllllblG is provided with a series of longitudinalslits 13, forming tongues 14, adapted to be bent radially against theinner wall of the flue and retain the thimhis in place. One or more ofthe end tongues 14, formed by the slits 13, are bent inwardly at rightangles to the longitudinal axis of the thimble, forming a stop or stops15 for the end of the pipe 11, preventing the same from projectingbeyond the end of the thimble and obstructing the flue. A collar 16 isalso provided, which rests on the stovepipe and also extendsover the earor cars 8 being locked against the 'face of the chimney-breast by thewire 10 passing through the opening in said ear or ears.

In practice the thimble is inserted in the opening in the chimney-breastwith the annular flange resting against the face thereof and the endtongues lebent radially against the inner wall of the fine by insertingthe hand or a tool through the thimble. The pipe is then placed in thethimble with the end thereof in contact with the stop, the pipe-collarfitting over the car, as shown, after which the wire is passed throughthe opening in the lug 8 and fastened in any suitablemanner to theelbow, (not shown,-) which secures the pipe and collar to the thimble.

In Fig. 3 I have shown a different manner of fastening the pipe to thethimble. In this case an opening 17 is punched or otherwise formed inthe pipe 11 coincident with the opening 9 in the ear 8, and a pin ornail 18 is passed through the two openings to secure the pipe to thethimble and hold the collar in proper position.

In some cases the flange at the outer end of the thimble may be formedby flaring the metal outwardly without the necessity of slitting, and insuch cases a pair of incisions or slits are made on the flange to formthe ear, as indicated at 8' in Fig. 4 of thedrawings.

Various changes in form, proportion, and

' mally outer end with an outstanding flange and a horizontallongitudinally-disposed finger having a perforation, and at its innerend with a series of tongues wholly surroundingthe thimble, one or moreof said tongues being bent inward to form a stop for the pipe and theremainder adapted to be bent out Ward for engaging the inner face of theflue- Wall, and means for securing the pipe to the thimble comprising amember engaging through the perforation of the finger and constituting astop for the removable collar.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two Witnesses.

CHARLIE E. HUBBS.
